COIN -CONTR.OLLED LOCK.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed March 27, 1916. Serial No. 86,901.

To all whom it may concern:

Be it known that I, ALBERT F. LESLER, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty of New York and State of New York, have invented a new andImproved Coin-Controlled Look, of which the following is a full, clear,and exact description.

This invention relates to looks and particularly to an improved coincontrolled lock and has for an object the provision of an arrangementwhereby the lock may be opened once from one side upon the insertion ofa coin and also opened once from the opposite side by reason of thatsame coin.

Another object in view is to provide an improved arrangement of lockwhich is coin-controlled and which is also key-controlled, thearrangement being associated with counters so as to indicate the numberof times the lock has been operated by a coin and the number of timesthe lock has been operated by the key.

A still further object in view is the provision of an improved lockespecially adapted for pay toilets, whereby the door may be unlocked onthe insertion of a coin, again locked when the door is closed andunlocked once from the interior for opening the door.

A still further object in view is to provide a coin controlled lockwhich, upon the insertion of a coin, may partially unlock and then. apull will completely unlock the mechanism so that the door to which thelock is secured may be opened whereby one unlocking is insured for theinsertion of each coin.

In the accompanying drawings Figure l is a top plan view of a lookembodying the invention, the same being shown applied.

Fig. 15 is an edge view of a lock showing the dials or faces of thecounting mechanism embodying certain features of the invention.

In constructing a lock embodying the invention it is aimed to provide agood looking mechanism and in addition a simple eiiective coincontrolled mechanism together with a number of operating parts adaptedto be actuated by a key. The lock is especially intended for use on thedoors of pay toilets and is intended to register each time the door isopened whether by a person depositing a coin or by a person operatingthe key mechanism. In addition, the mechanism is formed so that theinterior knob will operate the bolt for retracting the same once uponthe insertion of a coin but will not operate the bolt when the lock isopened by a key, so that a. person using the toilet and using the keymust leave the door open. This arrangement also prevents a second partyusing the toilet without paying as he would look himself in. To insurethe proper action of the bolt and to insure against operating the lookwithout opening the door, the mechanism is so constructed and arrangedthat when the outside knob is operated after the deposit of the coin thebolt will be retracted for part of its length and then will remainstationary regardless of how the CID knob may be turned, but will beretracted completely upon pulling the knob for opening the door. In thisway no one ever loses his coin as the knob merely retracts the bolt acertain distance and then is freed from the bolt so that all that isnecessary to do is to pull the door open. lhe same arrangement isprovided on the interior and when the interior knob has been operatedonce it frees itself from the bolt and all that it is necessary to do isto push the door open. In case the occupant attempts to operate the knoba second time, this may be done but will not accomplish any result.

Referring to the acco ipanying drawings by numerals, 1 indicates a doorof any desired kind to which the lock 2 is secured, said lock beingarranged exteriorly oi the door so that a coin may be placed in the coinslot 3 at any time. As shown in Fig. 1, the toilet to the door of whichthe lock 2 has been applied is vacant. Upon the insertion of a coin inslot 3 and then turning of the knob 1 the bolt 5 will be retracted untilthe point 6 will be substantially in line with the edge 7 of the casingof lock 2. The knob 1 cannot move the bolt in this position but if theknob is pulled outwardly and the door 1 opened the beveled or inclinedpart 8 will strike the socket member 9 and force the bolt in against theaction of a spring hereinafter fully described. As soon as the door hasbeen completely opened, or, rather, as soon as the bolt 5 has passed thesocket member 9, it will spring back to a full opened position and asdoor 1 is open by this time, this will have no effect. The personputting the coin in slot 3 will then enter the toilet and grasp knob 10and pull upon the same until the door is closed, the bolt 5 striking onthe inclined portion 11 against the socket member 9 in order to beretracted. The bolt in this manner snaps into a locked position in theusual manner of bolts now in common use. After this has taken place knob1 cannot again retract the bolt without the insertion of another coin.However, knob 10 may retract the bolt once, as hereinafter fullydescribed, so that the occupant may pass out whenever he desires.

The operating parts are shown in their assembled condition in Fig. 3 asthey would appear ii": the inner plate 12 of the casing 13 was removed,the section being taken approximately on line 3 3 01' Fig. 2. is shownin this figure (Fig. 3) the bolt 5 passes through a suitable opening inthe edge plate 14: of casing 13 and guided thereby and by the pin 15,which pin is rigidly secured to the casing by being screwed therein. Aspring 16 is connected with the casing and with the end of bolt so as tonormally hold the bolt in an outer position and to move the same to saidposition when released. Bolt 5 is provided with a hook 17, which hook isspaced an appreciable distance from what may be termed the body 18 ofthe bolt, said body being biturcated at the rear for accommodating pin15. One of the bifurcations of body 18 is provided with a projection 19having a notch 20 arranged therein, said notch accommodating theprojection 21 of a pivotally mounted member 22 held normally in a givenposition by a spring 523.

WVhen the bolt 5 is moved until the point 6 has reached the edge 7 ofthe casing, as shown in Fig. 1, the projection :21 will be in operativeposition and will hold the bolt against being projected by the spring16. Upon the pulling of knob at the bolt will be forced inwardly againstthe action ojt spring 16 until the door can be opened and also untilcatch or projection 21 has moved out of the notch 20, thus allowing thebolt to be again projected to its full outer position. As clearly shownin Fig. 1, the pivotally mounted member 2:2 is so arranged that the boltcannot return from the position shown in Fig. 1 until it has been fullyretracted, and then will freely pass the projection 21 withoutaccomplishing any results, said projection merely moving out of the way.A coin chute 2 1 is rigidly secured to the bolt and is arranged to guidethe coin to a coin receptacle 25, which coin receptacle may be of anydesired kind and which is preferably provided with a look so that theperson applying and removing the receptacle cannot examine the contents.In order to apply or remove the receptacle the lock 26 is operated,which look may be of any kind and which normally locks the door 2'?closed.

lVhenever it is desired to withdraw or retract bolt 5 through the use ofa coin, the coin is dropped into slot 3 and will pass from thencedownwardly into the coin wheel 28. It the word Vacant is disclosedthrough the opening 29 in the casing 13 the coin will be forced inposition and after the word Engaged is disclosed the section 30 of slide31 will cover slot 3 so that a coin cannot be inserted. After the coinhas been inserted the same drops into the wheel 28, as shown in Fig. 3,and lodges against pin 32 and wall'33, said wall and pin being arrangedto hold the coin so that the upper part will be flush with or above theperiphery of the wheel in order that the coin may engage the pin 34 andraise the same so that the pin will not lodge in the recess 35. Normallythe pin 34 is lodged in the recess 36 and if there is no coin in thecoin wheel the movement of the coin wheel is limited by the pin 3 1striking the bottom of the sockets and 36, such movement of wheel 28 notaccomplishing any results. Pin 31 is rigidly secured to an arm 37pivotally mounted at 38 to the casing and is held in proper position andcaused to press against the coin wheel by a spring 39. After the coinhas been inserted as shown in Fig. 3, the knob 4 is turned and coinwheel 28 is turned therewith until the parts assume the position shownin Fig. 4, whereupon the coin will drop out of the coin wheel into theguide 24 and from thence it will pass by gravity through slot 40 intothe coin box or receptacle 25. As the coin wheel 28 rotates the samecarries with it the pivotally mounted U-shaped member 43 which ispivoted at 44 on the Wheel, the pivotal member 45 extending through thewheel and having rigidly secured thereto on the opposite side an arm orlever 46, as shown more particularly in Fig. 7. The U-shaped member 43is provided with projections 47 and 48 with a socket 49 arrangedtherebetween. Socket 49 is intended to receive the pin 56 extending fromthe lever 57 connected with the counting mechanism 58, which countingmechanism may be of any desired kind.

When the wheel 28 moves it carries with it the U-shaped member 43 andthe extension 48 strikes pin 56 and consequently moves the lever 57 andcauses the counting mechanism to be operated for indicating that thelock has been operated once through the use of a key. The U-shapedmember 43 is provided with a pin 53 extending into slot 54 of the wheel28, said pin striking the coin and assisting in ejecting the same. Ifthe coin is not of the proper size, as for instance, if it is too large,the coin will not enter in between the walls 32 and 33.- If the coin istoo small it will enter and pass these walls and, in fact, pass entirelythrough the wheel 28, as the space between the walls 32 and 33 mergesinto a coin passageway 55. WVhen a key is used the U-shaped member 43 ismaintained in the position shown in Fig. 3 even when turned as shown inFig, 8 and hereinafter fully described, the holding of the parts in thisposition causing the U-shaped member to actuate pin 56 connected withlever 57 WVhen the wheel 28 first moves after a coin of the proper sizehas been inserted, the lug or extension 59 strikes the extension 60 ofthe plate 31 and slides the plate over to the position shown in Fig. 4.When the wheel moves back to its former position the lug 59 strikes pin50 and moves it back to its original position unless the same hasautomatically moved back upon the action of spring 61. A coin of theproper size is limited in its movement between the walls 32 and 33 by apin 32 projecting a short distance into the space between these walls sothat the periphery of the coin will be in line with or above theperiphery of the wheel 28. When the wheel 28 has been turned after thecoin has been deposited therein the coin will strike pin 34 and raisethe same so that the notch 35 may pass the pin 34 and the wheel rotatefor a sufiicient distance for causing the lug 50 to strike pin 50 andmove said pin together with arm 51 a sufficient distance for causing themechanism of the counter 52 to operate once, the slot 54 allowing thepin 53 of the U-shaped member 43 to slide and thereby not affect pin 50.If there is no coin inserted the wheel 28 will not rotate sufficient forthe projection 50 to strike pin 50 and therefore the counting mechanism52 cannot be operated. However, as above described, when a key isinserted the wheel 28 is moved so that pin 34 will engage the socket 35and at the same time the U-shaped member 43 will be rigidly heldsubstantially in the position shown in Fig. 3 with respect to the wheel28 so that when the wheel 28 is turned the projection 48 will strike thepin 56 as heretofore described for operating the counting mechanism 58.

The wheel 28 is provided with a stub shaft 41 on one side and with whatmay be termed a boss 42 on the opposite side, said boss being providedwith a slot 62 into which projects the lugs 63 and G4, which lugs areextensions of the tubular shaft 65 (Fig. 12) connected with the knob 4,the connection between the shaft 65 and knob 4 being by suitablefriction plates 66 and 67 of well known type the particular constructionforming no part of the invention, the connection in this way beingmerely for the purpose of allowing the knob to turn when a considerablepressure has been brought to bear thereon and when the shaft 65 islocked. Shaft 65 is provided with a slot 68 for accommodating thebifurcated plate 69 (Fig. 5) whereby the shaft is locked in the casing13. Shaft 65 is hollow and accommodates a pin 70, which pin is providedwith notches 71, which notches are designed to receive theend of a key72 passed through akey slot 73 in the shaft 65 so-that the pnrmay berotated by the key. The pin is rigidly connected with a lever 74, whichlever is provided with cutaway portions 7 5 and 76 in which the lugs (33and 64 move whereby there will be a lost motion, as these cutawayportions are of greater length than the lugs. This lost motion betweenthe parts permits the key to operate lever 74 for retracting the boltwithout operating the coin wheel 28 and the counting mecha nism 52.However, the shaft 65 when actuated by the knob will rotate the coinwheel 28 and if the pin 34 is caused to move out of the way by a cointhe wheel together with lever 74 will be rotated a certain distance forcausing said lever to strike against the lug 77. By a continued movementof the knob 4 the lever 74 will retract the bolt 5 until the notch 20has reached the projec tion 21.

The knob and associated parts are operated against the action of spring39, which spring is connected to the arm 37 and to the projection 80extending from the plate 69 so that the knob and associated parts willbe returned to.their former position when released. After the bolt hasbeen moved to the retracted position mentioned, that is, to the positionshown in Fig. 8, a pull on the knob will cause the door to open and inopening to retract the bolt to its extreme position and then release thesame so that it will be projected outwardly by the spring 16. In orderto withdraw or retract the bolt by the knob after a coin of the propersize has been inserted, it is necessary to move the wheel :28 fartherthan when a key has been used by reason of the cutaway portions 75 and76 on the lever 74;. It will be observed that lever 7% is provided withan upstanding member 81 which is adapted to engage the turned-up end 82of the arm as for holding the arm against a swinging movement when a keyis inserted, thus holding the U-shaped member 43 in its lowered or outerposition as shown in Figs. 3 and 8.

When a key is used the same is inserted as shown in Fig. 2 until the kevhas engaged the notches 71 of pin 7 0 so that upon turning of the keythe pin will be turned and the parts connected thereto. The lever 74: isrigidly secured to pin 7 0 and consequently turns therewith, and byreason of the cutaway portions and 76 this lever will turn for anappreciable distance before turning wheel 28 and will then, upon acomplete movement, turn the wheel 28 so that the pin 34.- will be insocket 35 approximately at the time the bolt has been retracted to theposition shown in Fig. 1-. In this way the wheel :28 is not turnedsufficiently for operating the counter 52 but is operated sufficientlyfor causing the rojection d8 to operate counter 58, which counterindicates the number of times the bolt has been retracted by the ke Itwill be observed that the wheel 28 when operated by a key is not rotatedsufficiently for causing the projection 59 to move slide 31 and alsodoes not operate to release the parts shown more particularlv in Figs. 9and 10 so that the inner knob cannot be actuated after the lock has beenoperated by a key. This necessitates the occupant leaving the door openunless he will lock himself in. As shown in these two Figs. (9 and 10),when the projection or lug 59 engages the extension 60 of plate 31 andmoves the plate to the position shown in Figs. 4, 9 and 10 the extension60 will also engage the upper end of lever 83 and move the lever fromthe position shown in full lines in Fig. 9 to the position shown indotted lines in said figure, thus causing the pin 8 1 to strike theinclined surface 85 of the pivotally mounted bar 86 and raise the sameso that the projection or catch 87 will move out of the notch 88 in thearm 89, which arm is rigidly secured to a shaft 90 which shaft extendsthrough the inner or back plate of the casing and has the inner knob 10connected thereto. The operation of the mechanism by a coin will causethe disengagement of the bar 86, which disengagement is maintained untilthe occupant turns the inner knob 10 and partially rotates the arm 89,said movement being sufficient to cause the pin 91 to strike the hook 17forming part of the bolt and re tract the bolt until the line or edge 6is in alinement with the edge 7 as indicated in Fig. 1. A push upon thedoor will then be sufficient to complete the unlocking and opening ofthe door as heretofore fully described. The knob 10 under the action ofspring 91' (Fig. 2) will automatically re turn to its former positionand will move the arm 89 back to its former position so that the catchor lug 87 will snap into notch 88 and thus lock the parts againstoperation until another coin has been deposited and knob i rotated.

In addition to the spring 91 moving the knob and associated parts backto their former position it also holds the knob 10 in an outer positionso that the pin 92 extending through the slot 93 of the shaft 90 cannotrotate said shaft until the knob together with its stem which carriespin 92, has been moved inwardly sufficient to cause the projecting end951 to move out of the notch 95 in the hub portion 96 of plate 97, saidplate being secured to the usual trinnning member 98 in which the shaftof the knob 10 is mounted, said trimming member being connected to thedoor 1 in any suitable manner, as for instance, by screws. The slot 93of shaft 90 is provided so that the shaft 90 maybe made of someconsiderable length in order that the lock may be readily applied todoors of different thickness and the pin 99. operate at any point in theslot. It will be noted that after a coin has been inserted it isnecessary merely to turn the outer knob and then pull the same in orderto open the door, while to open the door from the inside it is necessaryto push the knob inwardly and then turn the same in order to retract thebolt. Both knobs 1 and 10 are made identical in construction and areintended to rotate in case the same are forced, said rotation merelycausing the outer part to slip. In case the mechanism has been releasedeither by a key or by a coin the knob will then operate the parts asdescribed.

In arranging a lock in position 011 a door the same may be mounted inany suitable way, but the back plate of the casing is preferablyprovided with apertures 99 for receiving screws or other fastening meansand the large openings 100 through which the heads of screws may beinserted and then the back moved downwardly until the body of the screwengages the reduced openings 101 merging into the openings 100. This isvery desirable as it is necessary or at least preferable to secure thelock near the top and near the bottom. Near the top of the casing thevarious operating parts of the mechanism are mounted and it would bemore or less difficult to place ordinary screws therein, whereas thisconstruction will allow the easy placing of the retaining means inposition and the back plate thereon. In order to compensate for anyslight unevenness of the parts and the aperture through which the shaft90 passes, said shaft is loosely connected to the tubular member 102 bya pin 103, said tubular member being rigidly se cured to the arm 89 sothat the arm is rotated whenever shaft 90 is rotated. In connection witharm 89 a retractile or return pin 104 is provided, as shown in Fig. 10,for moving the lever 83 back to its former position when arm 80 has beenactuated so that when arm 89 moves back to its former orig nal positionthe catch 89 will snap into notch 88.
